Cat#:RP-4097H;Product Name:Recombinant Human IL15 Protein, HEK;Synonym:IL-15, IL15, Interleukin-15, MGC9721.;Description:Interleukin-15 Protein produced in HEK cells is a glycosylated monomer, having a molecular weight of 12.8kDa due to glycosylation. The IL15 is purified by proprietary chromatographic techniques.;Source:HEK.;Purity:Greater than 95.0% as determined by SDS-PAGE.;Bioactivity:The biological activity was determined by the dose dependent stimulation of the proliferation of CTLL-2 cells, the ED50 is typically less than 0.5ng/ml, corresponding to a specific activity of >2 x 106 Unit/mg.;Formulation:The IL-15 protein was lyophilized from 1842µl filtered (0.2µm) solution in PBS, pH 7.4 and 10% Trehalose.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:It is recommended to reconstitute the lyophilized IL15 with 2500µl PBS to a stock solution of 400µg/ml.;Storage:Lyophilized IL-15 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL15 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.;
